You can point to those civilizations because their collapse was not the end, life continued on. We haven’t been hit by a gamma ray burst or any other complex life ending disaster since we are here to discuss the scenario. But that’s no guarantee that we won’t be.
The odds of anything happening to render Earth totally uninhabitable are very small… in our lifetimes. But as long as we keep existing, the time frame will keep growing, the opportunities for disaster will keep accumulating and the odds will keep multiplying. The basic math looks very different when you multiply by infinity. Even the sun won’t last forever.
Obviously, this is no reason to neglect Earth and rush to other planets. But it is reason enough to reject the idea that we should never spread to other worlds because Earth will always be enough.

Of course. They would much rather see poor people with expensive needs die off. Your life has no value to these fascist ghouls. Not unless they can extract something of value from you.
The whole idea of a work requirement for medicaid is insane. You can’t mooch off healthcare to support yourself, it isn’t a replacement for income. If anything, this will only cause more people to become unable to work because they lose access to the care that helps keep them in the workforce.
It’s completely backwards. They want you to be outraged because some poor person might get government funded healthcare without having a job. The real outrage is that employers can pay workers a low enough wage that they need government assistance to make up the difference.
